3 Claims.

The present invention relates to improvements in television receiver picture window constructions.

The prior art includes a number of picture window constructions for television receivers, those appearing early in the development of the art. consisting only of a cut-out openingwith a vertically. oriented pane of glass disposed thereacross, and those produced at later stages of development of theart placing greater emphasis on appearance. It is .an object of the present invention to provide a picture window construction which affordsa wideangle of view, is decorative and attractive in appearance, is removable to permit ready access to both the cathode ray tube base and the rear side of the picturewindow to permit cleaning thereof, defines and masks the.picture opening, and at the same time maintains the picture window in such a position that glare is minimized.

For a better understanding of the present invention, reference is made to the following description of the accompanying drawings, in which there is shown a preferred illustrative form of picture window construction in accordance with the invention.

In the drawings:

Fig. 1 is a front view of the improved picture window construction which the invention features;

Fig. 3 is an elevational view of the right. side of the window construction;

Figs. 2, 4, and are sectional views taken along the section lines 2-2, 4-4, and 5-5 of Fig. 1, respectively, in each case looking in the direction of the arrows;

Fig. '7 is a rear view of the picture window construction illustrated in Fig. 1;

Fig. 8 is a top view as seen by an observer standing above and to the rear of the picture window; and

Fig. 6 is a bottom view of the construction illustrated in Fig. 7;

A generally rectangular opening formed in the vertical front panel it of a television receiver cabinet. This opening is concealed by a generally rectangular molding H which may optionally have a decorative theme as follows: an outer margin 12, an inner margin l3, and a central bead M. This particular decorative theme is featured in several models of television receivers marketed by the Crosley Division of the assignee of the present application and invention, the Avco Manufacturing Corporation, wherein the elements l2, l3, and M are collectively referred to as the Proscenium, Arch," margin, l2 beingfinished in mahogany, bead l4 in gold, and margin 13 in gray. Sectionally, margin l2 curves laterally outwardly and then rearwardly from head I4 until its edge terminates adjacentto the margins of the opening provided in. cabinet I9. The margin E3 of the molding ll converges inwardly and laterally toward the window panel5 until its inner edge terminates adjacenttthe window pane. of Figs. 2, 4, and 5 that the. lower generally horizontally extending run of the margin i3 is wider in a front to back direction than'the upper generally horizontally extending run of thatmargin, so that the window pane I5 is tilted downwardly and inwardly, the purpose of such tiltingbeing to minimize glare from reflected light.

It will be understood that any suitable decorative theme may be utilized in the molding l Lapplicant preferring those general themes shown and described in U. S. Design Patents 161,530, 161,531, 161,532, and 161,533, issued January 2...

invention, the window pane. I5 is positioned be tween the molding member H and a decorative mask member l5, which performs a number of functions: First, the definition of the picture opening; second, the provision of a decorative convergent stage around the opening; third, the positioniing of window pane l5; fourth, locking the removable assembly ofv molding, mask.

member, and window pane in place. The mask member is provided with an integral circumferential outer marginal flange IT. The outermost rim of this flange is generally rectangular, but.

it has rounded corners, as seen in Fig. 7. The main body of the mask l6 diverges or flares outwardly away from the cathode ray tube 22 as indicated at [8 and [9 in Figs. 4 and 5, respectively, terminating forwardly in a shoulder 20 which frontally abuts the window pane l5 and by complementary compressive action with margin [3 of molding H holds the window pane [5 in place. The upper portion of flange H, as illustrated in Fig. 4, is set back from shoulder 28 by an integral rearwardly extending portion 2| of the mask member, the width of this rearwardly extending portion 2| diminishing to zero at the lowest portion of the window pane, as illustrated in Fig. 5, whereat shoulder 20 is formed by a.

It will be seen from an inspection groove. Since the mask member diverges outwardly toward the front, it simulates the appearance of a stage in front of the cathode ray tube 22 and affords a wide angle of view to the observer.

Glued to the rear side of the molding are wooden blocks 23 through 35. Each of the blocks, with the exception of blocks 29 and 33, is formed with an arcuate forward bearing surface 3 which abuts against and is secured by glue to the inner side of margin 12, a cut-out upper integral shoulder 31 which abuts against the margin of the cabinet opening, an integral lower cut-out shoulder 38 which abuts against the front surface of window pane I5 (the references to upper and lower referring to Fig. 4), and a rear surface 39 which abuts against the front surface of flange H. A screw such as that illustrated at 40 is driven through flange H into block 23 to clamp together the mask member 16 and the molding l l, the shoulder 38 and the compression between margin l3 and shoulder maintaining window pane [5 in place. It will be understood that each of the blocks 23 through inclusive, with the exception of blocks 33 and 29, is similarly appropriately secured to flange I? by screws and is generally similar in construction to block 23 just described in detail.

Blocks 29 and 33 are identical, block 23 being illustrated in Fig. 5. Block 29 is provided with the usual bearing surface 4|, abutting and glued to the inner side of margin I2, and with a rear surface 42 abutting against window pane l5 and a cut-out shoulder 43 abutting against cabinet panel 10. The assembly of window pane l5, mask member I6, molding member ll, and the blocks other than 29 and 33 is maintained in position by an integral upwardly extending lip 45 centrally and upwardly formed by an extension of flange I! of the mask member and by two screws 46 and 41 driven through the outer margin i2 and blocks 33 and 29, respectively, into the front panel 10 of the cabinet (Fig. 5). When the screws 46 and 4! are removed, the subassembly is simply tilted outwardly and pulled downwardly to disengage it from the front panel i0 and to remove it from the television receiver cabinet.

This construction is particularly advantageous, not only because of its ready removability, pleasing appearance, and durability, but also because of the downwardly and rearwardly sloping position in which window pane I5 is maintained, glare thereby being minimized.

While there has been shown and described what is at present considered to be the preferred embodiment of the invention, it will be obvious to those skilled in the art that various modifications and substitutions of equivalents may be made therein without departing from the scope of the appended claims.

I claim:

1. In a television picture window construction for a television receiver cabinet of the type having an opening formed in the front thereof to expose a cathode ray tube screen, the combination of a decorative molding adapted to be disposed in front of the edges of said opening to conceal the same, a transparent pane disposed behind the inner margin of said molding, a picture-defining mask member, means for securing said pane in a sandwich-like assembly between said molding and said mask member, and means for securing the assembly of molding, pane, and mask member to said cabinet, said mask member being formed with an outer flange and a forwardly extending shoulder inwardly of said flange, said shoulder abutting against the rear surface of said pane and sloping downwardly and outwardly, the side portions of the inner margin of said molding member being tapered to tilt said pane inwardly with respect to the front of said cabinet.

2. A device in accordance with claim 1 in which said mask member comprises an integral flared portion converging inwardly toward the picture tube and away from said shoulder.

3. In a television picture window construction for a television receiver cabinet of the type having an opening formed in the front thereof to expose a cathode ray tube screen, the combination of a decorative molding adapted to be disposed in front'of the edges of said opening to conceal the same, a transparent pane disposed behind the inner margin of said molding, a picture-defining mask member, means for securing said pane in a sandwich-like assembly between said molding and said mask member, and means for securing the assembly of molding, pane, and mask member to said cabinet, the means for securing the molding and pane and mask member together comprising a plurality of clamping blocks each formed with a front bearing surface secured to said molding and integral shoulders engaging said pane and the edge of said opening,

said mask member being formed with an outer flange secured to said blocks.
